Google Ads API v26.1 released with network budget controls and external promotion redemption tracking

Google shipped Google Ads API v26.1, the first minor release under the new twice-monthly cadence, with no breaking changes. It adds a CustomerBudgetNetworkSetting resource and service for waterfall channel prioritization and budget caps, and an external_redeem_info field on promotion assets.

Other additions: a Local Services eligibility-check service and mutable redemption provider settings, household income exclusions for Performance Max through negative campaign criteria, an 'Optimize for new customers' recommendation type, reach reporting frequency buckets from six-or-more to nine-or-more plus metric state information such as privacy or quality suppression, new vertical ads reporting segments, and a new error that blocks activating a migrated Demand Gen campaign while its original or another migrated campaign is still active.
